Plz help. Saw them prolly early 90s. 1 about a bunch of dogs, kinda like pound puppies but better. Lots of diff dogs. I believe a railroad sog with the wooden barrel thing on its collar and one of those long haired dogs was a girl. Most lived in same house I think but more involved as well(srry not much to go on) I also think it was a series of sorts, not a movie. Now the crystal castle one had a bad guy running the castle, or palace. I believe in the end a piano of sorts struck a certain note and brought the castles crystals tumbling down. (I swear it was 1 of 3 or 4 cartoons on a vhs that included seabert as a cartoon, although my search attempts in that direction failed.) Any help appreciated. Love those oldies:)
